There's not much to describe. You either put bolts or rails (L-shaped) around the ports that you want to protect, preferably on the OUTside so the storm windows are "pushed" against the hull instead of being pushed away from the hull on the inside after the portlight has been smashed.

With the availability of Lexan and other polycarbonates, I think storm boards have somewhat gone out of fashion for those of us with smaller "glass" areas. Good idea if you have more exposure though.

I was helping a friend replace leaky portlights and we figured the only way to unstick the old ones was going to be imploding them and chewing the old frames out. he said no, that's lexan, you can't break that. Lots of folks think they have Lexan. I just swung the hammer, with just my forearm, and the portlight glazing all went away. I said "I don't think that's Lexan."
